Be it known thetl, JOHN B. Burner io- MEW, -a eilnzen of the UnitedStates, residing at Peomm'in the county of? Peoria and,

iii-brackets carried thereby; pivotally connected to o yoke j from Stateof Illinois, have invented certain new and useful Improvements inTraction-En gines, of which the following is e specifieation, referencehemg had therein to the ace The invention relates particularly toimprovements in tenderntteehments for tree: tion engines. v

' One of the objects of the invention is to pro 'ide'such an attachmentwith an improved wheelsupport and steering devices.

A further ohject is to provide in connection with the wheel. support ofthe tender impro ed coupler devices to which mtrailing' vehicle can. beattached, the-construction bemg such that the; action of the orait onthe coupler devlces has a certa n cooperative relation with the steerindevices.

The nature oi all of the various objects of the invention will heunderstood from the following detailed desorlption in connection withthe drawings. I;

tender frame. The two ring elements of the ball hearing are held inproper place relative to each other by means of the clamps or hook rodsP. The bars M project somewhat to the rear of the ball bearingand of thetender frame and are connected by a cross-plate or bar Q towhich issecured the rearwardly projecting coupler arm Q" adapted to have anothervehicle, as a threshing machine 'or the like, secured thereto. The wheelL serves not only as the onlysnpport for the tender but also as one ofthe steering devices by which the whole aIppat is turned on the verticalaxis of the ball hearing as follows& R is a cross bar secured to thesill beams E, E, of the engine frame near their front ends. It supportshorizontal pulleys 1', r. S, S are chains connected to the bar K of thefront steering apparatus and passing around the pulleys or sheaves 1'.Each chain is connected to a draft rod or link'T. At its rear end eachof these rods is connected to a chain U, the

strand u of which is at its end rigidly secured to the tender frame, itsother strand u extending backward and around one side of the ballbearing 0.. Each chain U is connected to its draft rod T by means of apulley V. The power for turning the rear wheel L can be transmitted toit with great ,efiiciency because of this manner of connecting thechains to the draft rods. The dimensions and positions of the variousparts are so roportioned that the rear wheel L shall properly ing asconcerns to the forward steering wheels D D. This supporting andsteering wheel L is constructed as a large hollow drum. It is built upof end plates L each of which is formed with a central hub l and withflanges or wings-Z The peripheral parts Z Z can be formed separately andthe parts can be all secured together by a series of thrqpigh bolts 7/.At the central transverse plane of the wheel, flanges, are formed asshown at l". When the wheel is made in two half shells those flanges canbe formed at the inner edges of the peripheral sections Z". The drumhowever can be made with .a' single peripheral part, in which case theflanges would be of the nature of ribs projecting from the outer surfaceof the wheel. A wheel of this character furnishes abroad base of supportfor the tender so that the weight thereof can be sustained at thesurface of the ground even though soft and tending to yield when pressedby a wheel. of ordinary dimensions.

The tender is formed with a central open chamber or space W forreceiving and retaining the solid fuel which is used in the e turned onits vertical axis to attain the best results in steertherelations ofthis wheel supporting and steering wheel L and is 'arranged to prov de aclearspace for the upper part of the wheel.

'The tender frame, it will be seen, can be so constructed as to beexceedingly strong and can be firmly attached to the rear end I of theengine frame. -The two sets of unit ing devices at M N and a beingremote from each other a wide/base of connection is provided and thetender frame is prevented from overturning. constructed and related inthe way shown and described the tender instead of increasing theresistance to, or difliculty in steering the advancing engine, when aload (such as athresher and separator) is' coupled behind the tender,reduces such resistance.

The load' helps the engineer to steer the engine and tender, as the loadis almost always pulling backin a line \vhicltassists in turning thewheel L in the desired (iii-cc tion. For example, if the severalvehicles coupled together are moving forward in a straight line, and itis desired'to travel in a curve to the right, the engineer, by hissteering shaft, throws the front steering wheels so that they will runin that direction, and thereupon two agencies come into play forcorrespondingly turning the tender, the first being the chains and linksabove described connecting the front steering gear with the frame of therear wheel L, and the second being the resistance from the third vehicle(the thresher or the like). When the. front steering wheels of thetraction engine are turned thus to the right,

the front end. of the traction engine frame begins to move to the rightabout a central 1 point located in the vertical plane of the axis of therear su 'iportin'g wheels ,(l-(l.

Necessarily the rear end of the traction engine and the tender is swungto the left about this same center, and the third ve hicle'coupled tothe frame of the wheel-L holds the rear end of this wheel frai'ne to Ifthe parts he the right, as the longitudinal lines of the traction engineare caused to assume an anglc of inclination with respect to thelongitudinal lines of the rear or third vehicle. The tender frame beingas aforesaid secured to the engine frame on a long line or base ofconnection the tender will not have any lateral movement relative to theengine, and consequently, the frame of the rear wheel L is compelled toturn to a degree proportional to the extent of turning the frontsteering wheels.
